Main Question or Discussion Point

my doubt is what is meant by rate of change of acceleration? how can i measure it in dyanmic condition? if it realated to machene tools, the movement of the slides acceleration has to be changed continuosly for different application . how we can measure it

The most direct way to calculate rate of change of acceleration (also known as "jerk")
is if you can measure the applied force on an object. The acceleration of the object will be the force divided by the mass (not weight, but mass) of the object.

The change in acceleration will be the change in force divided by the mass.

The rate of change of acceleration will be the change in acceleration divided by the time it took to make that change.

Edit: This process assumes that air resistance and friction are not a significant factor.

dear sir,

i want to know more about jerk only. please explai a bit


one of my friend mentioned in the front page itself that it can be measeured by usring accelorometer. how it exactly. works. i am not worried about plotting the results .but my thinking is how we can measure rate of cahnge of acceleration. just like speed is measeure by using speedometer. current by ammeter like that is there is any instrument to meausre jerk

thanking u
